Main shaft axostylus axostyle (Spindelwelle) in spindle nose accordingly can be rotationally supported individually.The torsion produced by spindle motor
Square is delivered to by attachment at the main shaft axostylus axostyle in spindle nose.In order to safeguard and maintenance work, spindle nose are removable
Unload, and replaced if necessary, by the identical spindle nose of structure.
In the spirit of the present invention, wording " vertical or horizontal Machining centers " is understood as such machining center, i.e. at it
In, work pieces process is implemented by vertical or horizontal alignment tool spindle.
A kind of driver under stress of the single type for machining center is elaborated in 20,11/,068 637 A1 of document WO
Tool spindle, it has the liquid cooling channel for the liquid cooling channel of spindle motor and for spindle nose, so that not
Only cooled down to spindle motor and to spindle nose.Two liquid cooling channels are connected to each other by interface.It is however, described
Bright tool spindle for single type driver under stress tool spindle, wherein, there is no by dismantle or replace be used as it is independent
Component spindle nose produce particularly simple maintenance the advantages of.
The instrument of the driver under stress of two-piece type is illustrated in document EP 1 609 549 B1 and document JP 3-142 142
Main shaft, it carries the liquid cooling channel in spindle motor housing and the liquid cooling channel in spindle nose housing.Pin
Event to this two-piece tool main shaft (it is with spindle motor and the liquid cooling channel being connected in spindle nose)
Barrier maintenance, disadvantageously coolant flows out uncontrolledly, because working as must tear open for maintenance work from remaining tool spindle
When unloading spindle nose, liquid cooling circulation portions will be opened.Here, on the one hand coolant can be invaded in the supporting of spindle nose,
Or on the other hand flow in the working chamber of tool spindle, in the cooling lubricant of this coolant pollution machining center.
The content of the invention
Based on the prior art, the tool spindle of the type referred to it is an object of the invention to provide beginning can be using it
Coolant is discharged into liquid cooling cycle portion before starting to dismantle spindle nose.The device should can be in terms of structure and processing technology
